Meet the DrinkMate: a small breathalyzer that plugs into your phone and helps you figure out whether you are sober. It plugs into your Android smartphone to display your Blood Alcohol Level. You just have to follow the instructions the companion app provides. The device does not have a battery and is powered using your Android phone. Power consumption ranges from 30 mA to 80mA. Considering that you don’t have to use this all day, that’s not too bad.
DrinkMate has an accuracy of +/- 0.01% BAC at a BAC of 0.02%. The maximum BAC is 0.20% BAC. The device measures 1.8″ long x 0.62″ in diameter and weighs 0.2 oz. Like what you see? You can support this project on Kickstarter.
